RESUMO
Objective To study the effect of maternal subclinical thyroid abnormalities [including subclinical hypothyroidism, hypothyroxinemia and positive anti-thyroid peroxidase antibody (TPOAb) with normal thyroid function] in women during 16-20 weeks of gestation on offspfing's intellectual development and motor function. Methods Sera from 1 268 women during 16-20 weeks of gestation (collected 2 years ago) were obtained and thyroid stimulating hormone (TSH), total thyroxine (TT4), free thyroxine (FT4) and TPOAb levels were measured. Pregnant specific thyroid function reference ranges were used to screen for subclinical hypothyroidism (18 cases), hypothyroxinemia (19 cases) and positive TPOAb (34 cases). From the same cohort, a total of 142 pregnant women who were euthyroid with negative TPOAb were selected as controls (a case: control ratio of 1 : 2). Intellectual and motor development score evaluations were performed in their children at 25-30 months of age. Results In the group of pregnant women with subclinical hypothyroidism, the offspring' s intelligence score was (109.89±13.81) points, which was 8.88 points lower than in the control group (P < 0.01). Similarly, the motor score of the offspring was (108.11±9.93) points, which was 9.98 points lower than in the control group (P < 0.01). In the pregnant women with hypothyroxinemia, the offspring's intelligence score was (112.32±15.10) points, 9.30 points lower than in the control group (P <0.01); the motor score was (112.21±12.26) points, 7.57 points lower than in the control group (P < 0.01). In the pregnant women with positive TPOAb and euthyroid function, the offspring's intelligence score was (112.70±20.64) points, 10.56 points lower than in the control group (P < 0.01); the motor score was (110.64±12.49) points, 9.03 points lower than in the control group (P < 0.01). Conclusion Maternal subclinical thyroid abnormality between 16-20 weeks of gestation adversely may affect offspring intellectual and motor development, suggesting the necessity for screening and treatment of maternal subclinical thyroid abnormality in the early stages of pregnancy.
RESUMO
Objective: To explore the characteristics of sensory behavior of autism children. Methods: 93 autism children between age 2 to 12, including 87 boys and 6 girls, were investigated based on Harrison's Sensory Behavior Scale. Results: Abnormal visual and auditory responses are quite common among autism children. Hyposensitivity to pain and overusing of smelling are less common. Significant differences were detected in auditory filtering, unusual visual response, hyposensitivity to pain and smell sensitivity between mild and severe groups. Conclusion: Autism children present varied sensory abnormalities. Severe autism children had significantly more sensory symptoms than the mild autism. The mechanisms for this deserves further exploring.
RESUMO
Objective:To analyse the behavioral problems of children with chronic tic disorders(CTD).Methods:Children with CTD only and with comorbid attention deficit hyperactivity disorder(ADHD)as well as ADHD and normal controls were assessed by Child Behavior Checklist(CBCL).The rates and scores of behavioral problems between groups were compared.Results:The rate of behavioral problems,total score and most subscales scores in CTD comorbid ADHD group and ADHD group were significantly higher than those of CTD only and control group.There were no significant differences between CTD only and control group except obsessive compulsive problem,hyperactivity behavior,aggressive behavior and total score.Conclusion:The present study suggests that comorbid ADHD was associated with more behavioral problems.
RESUMO
Objective: To analyse the behavioral problems of children with attention deficit hyperactivity disorder.Methods: 70 boys fulfilled ADHD criteria of DSM-IV were further divided into 3 subtypes: predominantly inattentive(PI,44 cases),predominantly hyperactive-impulsive(HI,6 cases) and combined type(CT,20 cases).Compare the behavioral problems of subtypes of ADHD and 63 normal children.Results: The incidence of behavioral problems in boys with ADHD(48.57%) was significantly higher than that in control group(12.70%),and significant differences in incidence of behavioral problems were found among the three subtypes of ADHD.ADHD CT subtype had the highest rate of behavioral problems.PI subtype had more fissility than HI;CT and HI subtypes had more aggressive behaviors,and HI had more delinquence than PI and CT.Conclusion: Boys with ADHD had more behavioral problems than normal ones.CT subtype had the highest rate.The characteristics of behaviors were different among three subtypes.
